4 Way Tire Inflation System with Closed Flow Chuck for Car Trucks Off Road Vehicles-Compatible with HPA Tanks and Compressors

100% independent review, I paid full price and am only offering my review because this product works great.I quickly deployed all 4 air chucks on each of my tires, no leaks and they were super easy to put on the valve. The pressure equalized between the 4 tires, then I added air and released some to get the pressure exactly where I wanted it with my gauge. I aimed for 33 lbs of pressure, which is what my tires suggest to use.This took seconds to do, super easy. After this, I removed the air chucks and I was surprised that no air leaked out, unlike other air chucks I have used where some air will leak when you disengage the device. Nope, these air chucks were better than anything I ever seen. I do not know why another reviewer had issues with them, they seem like good quality and sturdy. Just in case, I priced out and had in my cart 4 other, highly-rated air chucks to replace these if needed. Even with the additional price, this unit at the price point would still be substantially cheaper than the next unit's price. I doubt I will need to replace them anytime soon, they appear to be able to last years, they are all solid metal, and don't appear to be of poor quality.So now I went for a drive to let the Mercedes 2015 SL400 TPS sensors read the tires. I was delighted and surprised to see all 4 tires were exactly the same pressure. How I know the pressure is almost identical in all 4 tires is when I drive, the pressure will go up 1 or 2 lbs based on the outside temperature. I started out cold at 33lbs, and when I drove for a bit the pressure increased to 34lbs in unison on all 4 tires. I have never seen this happen before,m even when I had all 4 tires read the same pressure reading, usually 1 tire would increase before the others, and eventually all 4 would go up the the warm pressure setting. The tires are so close in pressure that they now go up together at the same time. not even new did my car ever do this.Definitely a keeper, I had a bag I could use to store the cables. A keeper for sure, thanks Amazon!

Works great. Easy to inflate and deflate tires on UTV and Jeep. Must have if you play in the sand or mud. Works quickly and is well made. Never had one before and would never go back to deflating an individual tire at a time.

Good product, but surprisingly, the air pressure does not balance between the four wheels. I even let them sit connected for 15 minutes after filling and they didn't balance (approx. 3psi difference). Seems to defy the laws of physics, and I am still having a hard time understanding why they will not balance. Ultimately, I had to fill each one separately to get the same pressure in each tire.

I've used this 3 times so far, and no issues at all! I was skeptical going with a "cheap" version of what usually costs $100 or more. They clip onto the tire valves easily and quickly. I use my large air pump to inflate all of the tires evenly, and simply roll it up for storage.

Works great and it packs up easy. I like that’s it’s a lot smaller than other versions. Might be a little stubborn in cold weather because the hose will be a lot less flexible.

Be warned, if you want to add valves, gauges or other accessories the threads are NOT standard USA measurements despite being labelled as so. They're clearly metric sizes which are 'closest' (and by closest I mean NOTHING FITS). Nor did any of my hose quick connections fit...and purchases to find the proper quick connect resulted in learning that the threads don't fit...I did manage to find some metric sizes eventually - so be warned. Otherwise it performs as expected.

I like that this manifold is compact and light so it does not take up a lot of space in the rig. I like to have the same tire pressure in all four for the TPS. I use it at home and to air up coming off the dirt. You could also buy new tubing and repair the manifold if you damage it.

My Toyota has the same pressure required for all tires, so particularly useful.
